Hi list !

Id like to know the width and height in pixels for a string given a
font family, size and style.
How could I do that ?

Thanks,
Stéphane.

This is undoubtedly overkill, but:

require 'tk'

f =3D TkFont.new('Courier 10')
width =3D f.measure("Hi There!")
height =3D f.metrics.assoc('linespace')[1]
